Haploids are more suitable for mutation studies than the diploids. This is because
Haploids are reproductively more stable than diploids
Mutagens penetrate in haploids more effectively than in diploids
Haploids are more abundant in nature than diploids
All mutations whether dominant or recessive are expressed in haploids
